I'm trying to find a cooling system leak in my 2011, 6.7. Just wondering what cooling system dye can be used in the Ford orange antifreeze.

 

Most UV dyes are compatible. I would start with a simple pressure test then add the dye if you could not find the leak normally.

If have been looking for this for a month, no drips on the driveway, no radiator leaks, oil looks good, truck just looses coolant???? You can smell it when you get out of the truck after a ride. coolant level seems to go down to just below the seam in the reservoir. takes a quart to fill it back up about every 500 miles.
Thanks for the video, ill check that out!

 

Ron made the greatest informational video's, report back on how it goes.
